The IoT (Internet of Things) sector
At NEXIO, we combine engineering (design and testing), measurement and simulation to offer tailor-made support to all business sectors.
Whether for components or complete systems, we operate on a global scale, respecting the standards in force (Europe, USA, Asia, etc.) and the specific requirements of each project.
We are committed to :
- Anticipate and master regulatory constraints right from the start of development.
- Identify and guarantee the essential functions of electronic devices.
- Minimize the costs associated with EMC/RADIO/DAS/Lightning development and certification sequences.
With over 20 years’ experience as specialists, we are well positioned to meet the challenges common to all sectors of the economy.
The IoT sector
The Internet of Things (IoT) sector is characterized by its unique features, which, although diverse, affect all industrial sectors. Connectivity-related functions are now ubiquitous, both in terms of applications and marketing.
Complexity and Multidisciplinary Approach
The diversity of applications, protocols, operating environments, consumption issues, as well as security and data management requirements, make this sector highly complex. Here are a few key constraints to consider:
-
Device heterogeneity and interoperability: A wide range of devices from different manufacturers must be able to communicate effectively despite technological differences.
-
Variety of protocols and networks: Technologies such as Wi-Fi, Bluetooth, Zigbee, LoRaWAN, NB-IoT and 5G offer compromises in terms of range, energy consumption, bandwidth and cost, as well as regulatory specificities.
-
Radio coexistence: The integration of several wireless links in a single device has functional and regulatory implications.
-
Power management / lifetime: the development of radio circuits and functions is directly affected by these crucial issues.
-
Varied operating environments: Devices can be deployed in harsh conditions (extreme temperatures, isolated natural spaces, industrial sites), influencing design choices.
-
Miniaturization: A general trend aimed at maintaining or even improving radio performance while reducing size.
-
Multidisciplinary approach: choices in mechanics, electronics, materials and software are all essential to the development and certification of radio functions.
